Therefore, when the black box falls into the water, the black box generally falls into the sea bottom, the sea current on the sea bottom generally continues to flow to one direction for a long time, and then turns, the sea current impacts the power wing, the power wing drives the power plate to move along the direction of the sea current, and further drives the supporting column, the suspension plate and the second sensing electrode plate to move along the direction of the sea current, and as the column sleeve on the elastic rubber cover is wrapped on the supporting column, the elastic rubber cover can freely perform elastic contraction and elastic expansion, the supporting column can freely move in the range of the circular limiting hole, and the power generation box body is in a sealed state; along with the movement of the supporting column, a part of springs in a second spring group fixedly arranged on the supporting column are compressed, and a part of springs are extended, so that when the comprehensive reaction force of the second spring group reaches a certain limit, the supporting column can be rebounded, and the suspension plate, the second induction electrode plate, the power plate and the power wing are driven to move back; along with the rebound of the supporting column, the comprehensive reaction force of the second spring group disappears, even elasticity in the opposite direction is generated, and at the moment, the power wing, the power plate, the supporting column, the suspension plate and the second induction electrode plate move along the direction of ocean current due to the power of the power wing impacted by the ocean current; so as to continuously and repeatedly move back and forth; in the repeated back-and-forth movement process, the first spring set also can elastically stretch and retract so as to drive the suspension plate to continuously move up and down and further drive the second induction electrode plate to continuously impact and rub the first induction electrode plate, when the friction occurs, the first induction electrode plate generates electrons, the second induction electrode plate receives the electrons, the surfaces of the two induction electrode plates are respectively provided with charges with opposite polarities, so that a potential difference is generated between the two induction electrode plates, the electrons are driven to flow in a reciprocating manner, and current is generated; and then connected to an electricity storage device through a wire, so that electricity is generated by using ocean current power.
